WINDOW-SCREEN FASTENING.

Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed April 27, 1904. Serial No. 205,145.

To ctZZ whom, it may concern:

Be it known that I, BYRD O. RocKWELL, a citizen of the United States, residing at Perla, in the county of Hot Spring and State of Arkansas, have invented a new and useful Window-Screen Fastening, of which the following is a specification.

My invention relates to window-screens, and.

has for its objects to produce a comparatively simple inexpensive device of this character adapted for ready adjustment to fit windows of varying sizes, one in which the terminal edge of the screen material adjacent to the open sides of the screen-sections will be securely bound and protected, the binding members serving to limit the extension of the screen-sections, and one in which the edges of the screen material will be securely and neatly attached to the adjacent rails, and this without the employment of a separate beading or molding.

With these and other objects in View the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is an elevation of a screen-section embodying my invention. Fig. 2 is a detail sectional view on the line 2 2 of Fig. 1. Fig. 3 is a similar view on the line 3 3. Figs. liand 5 are detail perspective views of connecting-clips. Fig. dis a detail view showing the meeting ends of a pair of screen-sections in their fully-extended position. Fig. 7 is a detail sectional elevation showing the rails of a pair of screensections connected. Fig. 8 is a detail perspective of one corner of the screen-frame, showing the parts disconnected. Figs. 9 and 10 are detail perspective views of other forms of clips. Fig. 11 is a perspective detail view, on an enlarged scale, showing a portion of one of the sections of a spring constructed in accordance With the principles of the invention. Fig. 12 is a perspective view showing one end of the binding member. Figs. 13 and 14 are sectional detail views showing the modified form of clips illustrated in Figs. 9 and 10 applied in operative position. Fig. 15 is a perspective view showing the form of clip illustrated in Fig. 4 applied to the end of a rail.

Referring to the drawings, 1 l designate the screen-sections, each comprising a top rail 2, a bottom rail 3, a vertical stile 4, and a sheet of wire-gauze or other reticulated material 5, attached to and carried by said parts, said sheet 5 being terminated short of the outer ends of the rails 2 and 3, or, that is, the ends disposed toward the open side of the frame.

The stile 1, constituting the side bar of the screen-frame, is composed of a front strip or section 6 and a rear strip or section 7, seated one upon the other, these strips, which are known to the trade as caps and backs, respectively, being adapted to receive between them the adjacent edge of the fabric 5. The back? of the stile terminates at its ends short of the ends of the latter, thereby producing rabbets 8, which receive the adjacent ends of the rails 2 and 3, the inner: faces of said rails being slightly recessed or rabbeted to produce seats for the ends of the caps 6 of the stile, whereby astrong neat connection is made between the parts of the frame at the corners of the latter.

Formed in the inner edges of the top and bottom rails 2 and 3 and adjacent to the inner side faces of the latter are slots or kerfs 9, which extend longitudinally of said rails from their inner ends to a point adjacent to their outer ends, where they terminate in sockets or recesses 10, formed in the inner side faces of the rails, these kerfs 9, which extend inward transversely a short distance from the inner edges of the rails, being designed as seats for the reception of the adjacent edges of the fab ric 5, which in practice is secured in place by small nails or other suitable fastening devices, the rails at one side of the kerfs being beveled or rounded, as at 11, to insure ready entrance of the fabric.

The outer or terminal edge of the fabric 5 is secured by a sheet-metal binding member 12, formed from a blank or strip of sheet metal of suitable length interfolded transversely throughout its entire length around the edge of the fabric, the blank adjacent to its ends being incised, as at 13, whereby its terminals may be compressed tightly upon the fabric, while its body portion between the incisions remains at an outward angular inclination sufficient for the edge 14 of the member to lie substantially flush with the adjacent inner faces of the rails 2 and 3, whereby when a pair of the cooperating screen-sections are extended, as illustrated in Fig. 6, the edges 14 of the binding members will abut, thereby limiting the relative movement of the screen-sections and,furthermore, preventing the passage of insects between the latter.

The rails 2 and3 have formed in their inner side faces, respectively, a pair of inwardlydivergent kerfs 15, disposed in spaced parallel relation throughout the entire length of the rails, said kerfs terminating at the outer ends of the rails in a pair of short supplemental parallel slots 16, extending entirely through the rails and producing intermediate tongues 17 and constituting seats for engaging members or clips 18, each of which terminates upon the inner face of the rail in a pair of outwardly-divergent tongues or portions 19, adapted to engage the corresponding kerfs in the rails of the companion screen -section, whereby the screen sections are securely united for relative adjustable movement, it being apparent that the engaging portions 19 of the clips of one section will during such adjustment travel longitudinally of the kerfs in the rails of the companion section.

As illustrated in Fig. 4, the clips 18 are provided each with a perforation 20 for the reception of a small nail or other fastening member, by which they are secured in place, while in Fig. 5 the clip is shown as having struck therefrom an outwardly-inclined tongue 21, which when the clip is seated in position will bite into the adjacent side face of the tongue 17 between the seating-slots 16 to prevent escape of the clip from the latter.

In Fig. 9 is illustrated a slightly-modified form of the clip having the engaging portions or fingers 19 formed by slitting the clip-blank transversely and bending said portions laterally therefrom in opposite directions, the body portion of the clip being a single flat metal plate having its upper edge downturned in the form of a flange 22, it being apparent that when this clip is employed a single longitudinal seating-slot will be formed for its reception in the end of the rail between the kerfs, while in Fig. 10 I have shown a further form of clip, differing from the clip of Fig. 9 only in that the body portion is folded back upon itself in substantially U form, thus providing a pair of parallel portions 23, which in practice enter longitudinal seating-slots formed in the end of the rail in a manner practically identical with that described in connection with the clips shown in Figs. 1 and 5. When these modified forms of clips are employed, the slots for the reception of said clips and the kerfs engaging therewith will be slightly modified, as will be seen by reference to Figs. 13 and 14: of the drawings; but in each case it will be seen that the body of the clip is seated in a slot or slots extending entirely transversely through the rail with which it is connected and that in no case is any portion of the body of the clip permitted to be interposed between the opposing or contacting faces of the rails of of a nail or fastening device or, as in Fig. 5,

a struck-up tongue, as 21; but in the form of the invention illustrated, for instance, in Fig. 9, the flange, there designated 22, will perform the distinct function of bearing upon the side of the rail opposite to that from which the tongues 19 diverge, thus holding the clip member securely against rocking or vibration.

From the foregoing it is apparent that I produce a simple inexpensive screen in which the sections will be securely connected for relative sliding movement, one in which the edges of the wire fabric will be in neat secure assemblage with the adjacent rails of the frame, and one in which entrance of insects between the screen-sections is obviated, it being understood that in attaining these ends I do not limit myself to the precise details herein set forth, as minor changes may be resorted to without departing from the spirit of the invention.

Having thus described the invention, what is claimed is 1. In an adjustable screen, a pair of longitudinally-adjustable rails having oppositelydivergent kerfs, the kerfs of each rail terminating in a pair of slots extending through the rail and separated bya tongue, and a clip seated in said slots in engagement with the tongue and having divergent portions for engagement with the corresponding kerfs of the adjacent rail.

2. In an adjustable screen, a pair of longitudinally adjustable rails having opposing faces adapted to contact with each other, said rails being provided with oppositely-diverging kerfs and with slots extending through the rails at the ends of said kerfs, in combination with clips bodily seated in said slots, secured against rocking movement, and provided each with divergent portions engaging the kerfs of the adjacent rail.

3. In an adjustable screen, a rail having divergent kerfs in the face thereof, an engaging rail having a clip-seat extending therethrough, and aclip engaging said seat, secured against rocking movement, and having divergent portions engaging the kerfs of the opposite rail.

4. In an adjustable screen, a pair of relatively movable screen-sections each comprising a frame and asheet of reticulated material, and sheet-metal binding members for the in- IIO ner edges of the reticulated material, said binding members having transverse incisions adjacent to their ends and the latter attached to the screen-frame, the body portions of the members between the incisions being angularly extended to lie in the path of each other to form stops and having their outer edges overriding the surface of the material of the adjacent screen-section.

5. In a screen, a frame and a sheet of reticulated material carried thereby a binding member for one edge of the material, longitudinal kerfs formed in a pair of the framebars and constituting seats for the adjacent edges of the material, said kerfs terminating in seats for the ends ofthe binding member, and means for securing the latter in place.

6. In an adjustable screen, a pair of relatively and longitudinally adjustable rails, one of said rails having a pair of divergent longitudinal kerfs and the other a longitudinal clipseat extending through the body of the rail,. a clip having a body portion engaging said seat and projecting divergent portions for engagement with the kerfs, and means for securing said clip againstrocking movement.

7. In an adjustable screen, a pair of relatively and longitudinally adjustable rails, one of said rails having a pair of divergent longitudinal kerfs and the other a pair of slots producing an intermediate tongue, and a clip having a body portion engaging said tongue and divergent portions for engagement with the kerfs.

8. In an adjustable screen, a rail having a pair of divergent kerfs terminating in a clipseat extending through the body of the rail, a clip having a body portion engaging the seat and divergent portions projecting beyond one face of the rail, and means for securing said clip against rocking movement.

In testimony that I-claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
